Only as a watermark. AFAIK there is no feature to read and write the Capture date and time on top of an exported image. But that info is included with the exported image in the EXIF Metadata unless you specifically select to remove it from the export.

I am not sure if I actually have the .exe file as
there is no file with that extension in the folder.
